I'm testing our software with several versions of Java 8. It works fine with RedHat's and Zulu, but with IBM's Java 8, it's throwing the following exception:
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException:
Line 1 in XML document from file
[C:\xxxx\image-server\.\res\conf\temp.xml] is invalid;
nested exception is org.xml.sax.SAXParseException:
cvc-elt.1: Cannot find the declaration of element 'server'.
The temp.xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?><server id="myServer" max-logins="100" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://mina.apache.org/ftpserver/spring/v1 http://mina.apache.org/ftpserver/ftpserver-1.0.xsd">

</beans:bean>
</beans:property>
</beans:bean>
</ftplet>
</ftplets>
<file-user-manager file="./res/conf/icr890usersfile.properties"/>
</server>
Any idea what the problem might be? Why just IBM's implementation?
Edit: additional info
The "server" element which isn't being found is from the apache mina project.
https://mina.apache.org/ftpserver-project/configuration_server.html
<server xmlns="http://mina.apache.org/ftpserver/spring/v1"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://mina.apache.org/ftpserver/spring/v1 http://mina.apache.org/ftpserver/ftpserver-1.0.xsd"
id="server"
max-logins="500"
anon-enabled="false"
max-anon-logins="123"
max-login-failures="124"
login-failure-delay="125">
...
</server>
A similar (but not the same) error appears in a bug report for mina ftp:
https://issues.apache.org/jira/browse/FTPSERVER-458
The comment on that was:
"The schema is located in ftpserver-core-1.0.6.jar/org/apache/ftpserver/config/spring/ftpserver-1.0.xsd.
This is a configuration problem, ftplets element should be placed before file-user-manager."
I wonder if this is a classpath or classloading issue, since the xsd is found in a jar file.
Edit:
This project is using a schema setup as described in the section "Appendix B. Extensible XML authoring" in the Spring docs at https://docs.spring.io/spring/docs/3.0.0.M3/reference/html/apb.html.
Besides setting up a schema, it has you create two properties files under META-INF: 1. spring-handlers, which maps the xsd to the custom handler (based on the targetNamespace in the schema).
The contents of this are:
http://mina.apache.org/ftpserver/spring/v1=org.apache.ftpserver.config.spring.FtpServerNamespaceHandler
Note the backslash after the "http" is required for the colon.
So the name matches as per the instructions.
- The properties file called 'spring.schemas' contains a mapping of XML Schema locations to classpath resources.
The contents of this second one look like this:
http://mina.apache.org/ftpserver/ftpserver-1.0.xsd=org/apache/ftpserver/config/spring/ftpserver-1.0.xsd
So, unusually for a resource, the XSD is distributed in the jar file at the same level as the handler class.
